CVE-2025-54160
📋 TL;DR
This path traversal vulnerability in Synology BeeDrive desktop software allows local users to execute arbitrary code by manipulating file paths. It affects users running BeeDrive desktop versions before 1.4.2-13960 on their local systems.
💻 Affected Systems
- Synology BeeDrive for desktop
⚠️ Risk & Real-World Impact
Worst Case
Local attacker gains full system compromise with administrative privileges, potentially leading to data theft, ransomware deployment, or persistent backdoor installation.
Likely Case
Local user or malware with user-level access escalates privileges to execute arbitrary code, potentially compromising sensitive files and system integrity.
If Mitigated
With proper user access controls and endpoint protection, exploitation would be limited to already compromised user accounts with local access.
🎯 Exploit Status
Requires local access but unspecified vectors suggest multiple potential exploitation paths.
